一行:

 mysql -u root -p dbName -e 
 "show table status where Engine='MyISAM';" | awk 
 'NR>1 {print "ALTER TABLE "$1" ENGINE = InnoDB;"}'  | 
  mysql -u root -p dbName

一行:

 mysql -u root -p dbName -e 
 "show table status where Engine='MyISAM';" | awk 
 'NR>1 {print "ALTER TABLE "$1" ENGINE = InnoDB;"}'  | 
  mysql -u root -p dbName

<?php

  // connect your database here first

  mysql_connect('host', 'user', 'pass');

  $databases = mysql_query('SHOW databases');

  while($db = mysql_fetch_array($databases)) {
    echo "database => {$db[0]}\n";
    mysql_select_db($db[0]);

    $tables = mysql_query('SHOW tables');

    while($tbl = mysql_fetch_array($tables)) {
      echo "table => {$tbl[0]}\n";
      mysql_query("ALTER TABLE {$tbl[0]} ENGINE=InnoDB");
    }
  }

对于转换MySql表存储引擎有许多方法:

使用MySql命令如下，转换为innodb (ALTER TABLE t1 ENGINE = innodb)或(ALTER TABLE t1 ENGINE = MyISAM)为MyISAM(你应该为每个单独的表这样做，t1是表名。) 编写一个在所有表上循环的脚本，并运行alter命令 使用一个已经可用的脚本来处理这个问题:https://github.com/rafihaidari/convert-mysql-tables-storage-engine

在phpMyAdmin中使用此sql查询

SELECT CONCAT('ALTER TABLE ',table_schema,'.',table_name,' engine=InnoDB;') 
FROM information_schema.tables 
WHERE engine = 'MyISAM';

一个简单的MySQL版本。

你可以简单地启动mysql可执行文件，使用数据库和复制粘贴查询。

这将把当前数据库中的所有MyISAM表转换为INNODB表。

DROP PROCEDURE IF EXISTS convertToInnodb;
DELIMITER //
CREATE PROCEDURE convertToInnodb()
BEGIN
mainloop: LOOP
  SELECT TABLE_NAME INTO @convertTable FROM information_schema.TABLES
  WHERE `TABLE_SCHEMA` LIKE DATABASE()
  AND `ENGINE` LIKE 'MyISAM' ORDER BY TABLE_NAME LIMIT 1;
  IF @convertTable IS NULL THEN 
    LEAVE mainloop;
  END IF;
  SET @sqltext := CONCAT('ALTER TABLE `', DATABASE(), '`.`', @convertTable, '` ENGINE = INNODB');
  PREPARE convertTables FROM @sqltext;
  EXECUTE convertTables;
  DEALLOCATE PREPARE convertTables;
  SET @convertTable = NULL;
END LOOP mainloop;

END//
DELIMITER ;

CALL convertToInnodb();
DROP PROCEDURE IF EXISTS convertToInnodb;
